Morse TrainingWilliam G. Pierpont NØHFF 1915-2003 The Art and Skill of Radio-Telegraphy http://www.qsl.net/n9bor/n0hff.htm • Aural memory –letters → words → thoughts Burn those code charts! • Begin with Farnsworth speed: letter speed > word speed • Skilled Morse is fun – relax with a positive attitude! • Overlearning is the secret of real proficiency. Examples: OCEAN RIVER VALLEY THE OCEAN YOUR OCEAN REFUSES NO RIVER = THE RIVER MAKES THE VALLEY AND THE VALLEY HOLDS THE RIVER =
Morse Training, cont.William G. Pierpont NØHFF 1915-2003 Four Principles of Learning Morse: • Concentrate on one aspect at a time: • Don’t try to learn block printing or typing at the same time. • Learn to receive the code accurately. • Copy behind rather than guessing ahead. • Listen only to accurately-sent code. • Plan for regular daily practice periods.
